We have 2 Win7-64 bit machines that we need to be able to remotely log these machines back in if they crash.

Unaware of the problem, the first time one of the PCs crashed, I tried to log it back in and, of course CAD button from VNC didnt work.

I started looking on the web and found a post that said you needed to enable SAS in local policy so I did that on one of the machines. Then I launched VNCviewer from a 32-bit xp client and attempted to log in to the Win7 machine - still no CAD.

I found another post that says you have to drop CAD.exe and SChook.dll into the VNC folder. I did so on the Win7 (server) machine and tried to log into it again from the XP-32bit viewer - still no luck

The problem is I cant find any cohesive information for attacking the problem: just bits an pieces. Can anyone provide step by step instructions for solving this problem.

Both the viewer and the server are running 1.0.8.2. Any help would be appreciated.

First, it helps to be running as a service. Second, it helps if UAC is turned ON (I know, ridiculous, blame Microsoft). Third, the new 1.0.9.x versions supposedly do away with the need for CAD.EXE but I haven't tested them yet.
